Abstract It is still very challenging to obtain colorful and long‐afterglow room‐temperature phosphorescent (RTP) materials from pure organic polymers. Herein, it found that chitosan (CS), a natural polymer, not only has its own RTP, but also reacts with different molecules multicolor, RTP material. CS can emit lifetime of 48 ms. In addition, rich in amino groups, grafting onto by an amidation reaction modulate colors phosphorescence series derivatives. The obtained polymer films have...
Here, we constructed a nanostructured pH/redox dual-responsive supramolecular drug carrier with both aggregation-induced emission (AIE) and Forster resonance energy transfer (FRET) effects, which enabled selective release monitoring delivery processes. Taking the hyperbranched polyamide amine (H-PAMAM) intrinsic AIE effects as core, poly(ethylene glycol) (PEG) was bridged on its periphery by dithiodipropionic acid. Then, through host–guest interaction of PEG α-cyclodextrin, nanoparticles...
Aberrant production of H2O2 is involved in cancer. The levels are significantly higher tumor cells than normal cells. It important to develop fluorescent probes image basal selectively So far, a cancer cell-targeting probe has not been reported. Thus, we developed probe, BBHP, which contains benzil as H2O2-recognition site and biotin target binding motif for the selective sufficient detection BBHP enables fluorescence turn-on response H2O2. with receptors can greatly accelerate As result,...
Facing the global health crisis caused by drug-resistant bacteria, antimicrobial peptides and their analogues offer exciting solutions to this widespread problem. Without additionally introducing a fluorescent probe, novel nanoengineered peptide-grafted hyperbranched polymers (NPGHPs) are constructed for combined outstanding activity sensitive bacterial detection in real time. Hyperbranched polyamide amine (H-PAMAM) that exhibits aggregation-induced emission (AIE) effects is synthesized....
Photothermal therapy (PTT) offers significant potential in cancer treatment due to its short, simple, and less harmful nature. However, obtaining a photothermal agent (PTA) with good performance biocompatibility remains challenge. MXenes, which are PTAs, have shown promising results treatment. This study presents the preparation of Ti
Abstract An antibacterial polymer peptidopolysaccharide (COS‐AMP) that integrates and detection functions is constructed with a simple synthetic method. The COS‐AMP by simulating the structure of peptidoglycan bacterial cell wall chitooligosaccharide intrinsic aggregation‐induced emission (AIE) effect as main chain, well peptide grafted onto its amino group. Based on AIE excitation‐dependent fluorescence COS‐AMP, it tentatively applied to multicolor imaging quantification bacteria. This...
Exploring the applicability of next-generation pure organic room-temperature phosphorescent (RTP) materials has become a research focus in recent years. Herein, simple strategy for preparing long-lived polymer aerogel temperature sensor with an ordered structure as well thermal insulation was presented. Based on noncovalent interactions between poly(vinyl alcohol) (PVA) and melamine formaldehyde (MF), composite (PVA-MF) excellent stability, extremely low conductivity, outstanding fire...
A new route to form multiple morphologies was outlined using amphiphilic graft copolymers with interesting biological and pharmacological properties by proper adjustment of backbone chain length.
Biomedical magnesium is an ideal material for hard tissue repair and replacement. However, its rapid degradation infection after implantation significantly hindersclinical applications. To overcome these two critical drawbacks, we describe integrated strategybased on the changes in pH Mg2+ triggered by magnesiumdegradation. This system can simultaneously offer anticorrosion antibacterial activity. First, nanoengineered peptide-grafted hyperbranched polymers (NPGHPs) with excellent activity...
Abstract In previous studies, crystalline precipitates, not stable hydrogels, were obtained when low‐molecular‐weight (MW) poly(ethylene glycol) (PEG; weight‐average MW = 400–5000) was used to interact with α‐cyclodextrin (α‐CD). this study, the gelation ability of low‐MW PEG (number‐average 2000, PEG‐2000) and α‐CD systematically investigated through variation in concentration PEG‐2000 water ( C ) feeding molar ratio repeat unit R ). The results show that a supramolecular hydrogel could be...
